illustrated in Figures 6 and 7 can be used in the same manner as theother tool described.

WVhat is claimed is:

1. A cutting tool including clamping plates eaeh having one side edgecut away and. an opposed corner portion cut away, laterally extendingwings on the plates constituting obliquely disposed runners, handleportions integral with the plates, a cutting blade interposed betweenthe plates, a portion of one edge of the blade being exposed between thecut away edges or" the plates and cooperating with the runners to'vforma crotch for receiving material to be cut, one corner portion of theblade being extended beyond the cutaway corners of the plates, and meansforbindingi the plates upon the blade. r r

2. A cutting tool including separate clamping plates each having ahandle portion, a two-edgedcutting bladehaving portions of:

1 'said edges exposed beyond the edges of the plates, Ineansfor clampingthe plates upon the blade and the handle portions against; each othenanda projecting ear on one of the plates, said ear and an exposed portionof the cutting edge of the blade cooperatingto simultaneously crease amaterial andcut through the material along the crease; I a In testimonythat]: claim the foregoing as my own, I have hereto afiixedmy signature:
